The OPA1656 is a Burr-Brown™ operational amplifier (opamp) designed specifically for audio and industrial applications where maintaining signal fidelityis crucial. The FET-input architecture achieves a low 2.9-nV/√Hz voltagenoise density and 6-fA/√Hz current noise density, allowing for very lownoise performance in a wide variety of circuits. The high bandwidth, high open-loop-gain design ofthe OPA1656 delivers a low distortion of 0.000035% (–129 dB) at 20 kHz, which improves audio signalfidelity across the full audio bandwidth. This device also features excellent output current drivecapability, offering rail-to-rail output swing to within 200 mV of the power supplies with a 2-kΩload, and can deliver 100 mA of output current.

The OPA1656 operates over a very wide supply range of ±2.25 V to ±18 V or (4.5 V to 36 V)on 4 mA of supply current to accommodate the power supply constraints of many types of audioproducts. The temperature range is specified from –40°C to +125°C, and is offered in a 8-pinSOIC.
